WINDOW-BLIND FASTENER.

SPECIFICATION forming part of Letters Patent No. 780,417, dated January 17, 1905.

' A li ti fil d April 13, 1904. Serial No. 202,895.

To (LZZ whont it may noncern:

Be it known that I, THEOPHILE EUPHRAT, a citizen of the United States of America, and aresident of Norwalk, countyof Fairfield, and State of Connecticut, have invented certain new and useful Improvements in VVindow- Blind Fasteners, of which the following is a specification.

My invention relates to means for fastening window-blinds in the closed position more securely, more conveniently, and more efliectively against rattling by the wind when open, as hereinafter described, reference being made to the accompanying drawings, in which Figure 1 is a horizontal section of a window with closed blinds, illustrating the general construction of my improved blindfastening. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is a detail in section on line 3 3 of Fig. 1. Fig. 4 is a section on line 1 1 of Fig. 3. Fig. 5 is an elevation of a modified form of fastening-bolt shown in Fig. 4. Fig. 6 is a section on line 6 6 of Fig. 4. Fig. 7 is a plan, partly in horizontal section, of a modification of the fastening-bolt.

A represents a tubular case placed on the upper surface, or, if preferred, embedded in the sill a of the window-frame transversely, with its outer end flush with the outer edge of said sill on that side of the central meeting line of the blinds Z2 upon which the outer overlapping member 0 of the rabbet meeting-joint is. In this example of my invention said case extends through the sill a to the inside, and near the outer end it is fitted with internal shoulders d and stops e. A portion of the inner space of the case forms a socket f, in which is a spring in for retracting the hook described farther on.

The blind c has a recess g, which coincides with the outer open end of the case A when the blind is shut, which recess is covered by a slotted plate 71., and a hook-bolt 5, having hook-heads j, is arranged in the case A, with its hook-heads projecting so as to reach through the slotted plate and hook inside of it to hold slotted plate A.

the blind closed, said bolt having a spring 1: applied in a manner to maintain the hooked connection and keep the blind closed. The hook-bolt and the spring may be contrived in various ways. In Fig. 1 I show a split bolt of springy material, whereof the separated parts have naturally expanding tension and being formed with book endsj projecting in opposite directions and shaped suitably to be forced through the slot of plate It, and thereby be partly closed, open when through and engage the plate and fasten the blind. Inside of the mouth of the case A the said separated parts or jaws Z have inclined fins m, which being thrust against the shoulders (I close the jaws Z and release the hook-heads j from the plate h when it is wanted to open the blinds, the hook-bolt i being for this purpose extended inward beyond the end of the case and the spring is being applied behind the head 11. of the bolt suitably to permit such thrust and to return the bolt to the normal position and to hold the blinds when engaged therewith against rattling.

The hook-heads, as 3', Fig. 7 may be formed on springy arms Z of a tubular and fixedlyplaced bolt 01, suitably fixed in the case A, with a sliding yoke 0 suitably arranged on. them to close and release them from the slotted plate it, with a push rod 12 extending from said yoke beyond the inner end of the bolt and having a push-stud q, with a spring 1" between said push-stud and the end of the bolt for retracting the yoke and allowing the hooksto open and engage with said slotted plate, and a bolt, as t, with a fiat solid hookhead j may be employed with a spring .9 to normally hold the bolt with the head crosswise of the slot in the plate 11 the bolt being shifted a quarter of a turn by the operator to pass the head through the slot when the bolt is to be engaged with or disengaged from the In this case the knob t will have less projection inward.

What I claim as my invention is 1. The combination with the window-sill and 5 adapted for said hook-head to be inserted through it, spring means to normally cause said hook-bolt to assume a hooked engagement with said slotted plate when inserted through said slot and means for unhooking 10 the bolt by the head of'the stem extended inside of the window.

2. The combination with the window-sill and the blinds, of a hook-headed bolt applied to the sill with its hook-head extended to reach into 5 a recess of the blind when the blind is closed,

a slotted catch-plate on the blind adapted for said hook-head to be inserted through it, expanding spring-jaws carrying said hook-head and engaging said head with the catch-plate 20 when inserted through it, and means for contracting said jaws to release them from said slotted plate, said means operated by the 1nstrumentality of the stem of the bolt extended inside of the Window.

3. The combination with the window-sill and the blinds, of a hook-headed sliding bolt applied to the sill with its hook-head extended to reach into a recess of the blind when the blind is closed, a slotted catch-plate on the blind adapted for said hook-head to be inserted through it, expanding spring-jaws carrying said hook-head and engaging said head with the catch-plate when inserted through it, inclines and shoulders for contracting and releasing the hook-head when thrust forward, and a spring for retracting the sliding bolt and engaging the hook-head with the slotted plate.

It is hereby certified that in Letters Patent No. 780,417, granted January 17, 1905 upon the application of Theophile Euphrat, of Norwalk, Connecticut, for an improve ment in Window-Blind Fasteners, errors appear requiring the following correction viz: In the grant and in the printed head of the specification it is stated that said applicant had assigned three fourths to the Hurwood Manufacturing Company, a corporation of Connecticut, and George J. Tischer of New Haven, Conn, whereas it should have been stated that said applicant had assigned one half to the said The Hurwood illanufactu'ring Company and one fourth to the said George J. Tischer; and that the said Letters Patent should be read with these corrections therein that the same may conform to the record of thecase in the Patent Oflice.
